Problem importing important functions into new packages

[Issoufou-Liman]

It would be great to have some the functions in generics.R file (e.g. nodestates, nodeNames) exported for use in other packages. Can we expect this to happen any soon?

I suspect the author don't want to clutter up the namespace with functions that most people don't ever need. The methods you refer to are nothing but getter-methods around a list object (which a grain object is). If you look inside grain-utilities.R you see the workhorse getgrain; and it simply uses the extractor function $. So nodeStates is just object$universe$levels[nodes-of-interest] and nodeNames is just object$universe$nodes. So you easily can define your own methods in your package around a grain object. And since getgrain is an exported function it is just as convenient to exploit that function.

And looking inside your repo

https://github.com/Issoufou-Liman/decisionSupportExtra/blob/2a6cd749dbdfcb90880c174260aa0ee49ed06642/R/check_bn.R

it seems that you have already done exactly as above ;)
